Night sweats waking me up
You fall asleep fine. Then you wake up hot and damp. Your top sticks to you and the sheets feel cold.
The heat passes in a few minutes. Then you shiver and lie wide awake. Some people change their shirt or their sheets before they can settle again.
Around menopause, this is often the same hot flush people get in the day. It just lands while you are asleep. Broken sleep is the part that wears most people down.
Night sweats have other causes too. Some are easy to fix. A few need a doctor, so it is worth knowing which one fits you.
When to see someone
Call your doctor this week if you bleed after your periods have stopped. That always needs a check.
See a doctor if you lose weight and you did not try to. Go too if you have a fever, chills, or a cough that will not clear.
Book a visit for new lumps or swollen glands. Check your neck, armpits, and groin. Soaking sweats most nights for three weeks or more need a check too.
Tell your doctor if you snore loudly or gasp in your sleep. That points to sleep apnea. A sleep test can sort it out.
If you take insulin or diabetes pills, test your blood sugar when you wake up sweaty. Low readings at night need a call to your doctor. Your dose may need a change.
Go to urgent care or the emergency room for chest pain or trouble breathing. Go for a fever over 103F, which is 39.4C. Go if you feel very unwell and cannot keep fluids down.
Also see a doctor if night sweats started soon after a new drug. Do not stop the drug on your own. Ask what else you can take.
Why it happens
As menopause nears, your ovaries make less estrogen. The part of your brain that tracks body heat gets touchy. A small rise in heat now reads as far too hot.
So your body dumps heat fast. The blood vessels in your skin open wide. You sweat, the sweat cools you too much, and then you shiver.
Night adds fuel. A warm room, a thick quilt, wine, or a late spicy meal can tip you over the line. Your own body heat also rises and falls on its own while you sleep.
What else it could be
Menopause sweats usually come with other clues. You get flushes in the day too. Your periods have changed, spaced out, or stopped.
An infection can cause night sweats. But you feel sick with it. Look for fever, chills, body aches, or a cough that hangs on for weeks.
An overactive thyroid speeds your whole body up. You feel hot all day, not just at night. Shaky hands, a racing heart, loose stools, and weight loss are common signs.
Medicines are a very common cause. Antidepressants top the list. So do tamoxifen, steroids, some pain drugs, and drugs for fever.
Low blood sugar wakes some people in a sweat. This hits people who take insulin or certain diabetes pills. You wake damp, shaky, and hungry, and food fixes it fast.
Sleep apnea can wake you hot and gasping. Loud snoring is the main clue. A bed partner often spots it before you do.
Anxiety and bad dreams soak some people too. Your heart pounds and your mind races. With these, the sweat tends to start as you wake, not before.
Alcohol in the evening warms you, then wakes you a few hours later. A hot room or a heavy quilt does much the same. These sweats stop when the cause stops.
Rarely, night sweats point to something serious, such as lymphoma. The clue is the mix. Drenching sweats plus weight loss, fever, and new lumps needs a doctor now.
How to read the grades below
The options below come from our page on Menopause. Each one carries two labels.
The first label is the evidence grade. A means strong trials in people, B means smaller or mixed studies, and C means early or limited findings. D means lab work only, and “insufficient” means the research cannot settle it yet.
The second label is the traditional tier. T3 means long use in more than one tradition, T2 means long use in one, and T1 means known use. T0 means no such record.
These grades come from research on Menopause, the parent Health Topic, not on night sweats waking me up.
A grade tells you how strong the research is, not how well something will work for you. Talk to a doctor or pharmacist before you start anything, above all if you take other medicines.
What to try first
Start with the room and the bed. Keep the room cool. Thin layers you can kick off are one option for bedding and sleepwear.
Cotton or wicking sleepwear helps. Keep a glass of cold water by the bed. Keep a dry top there too.
Some people find that less wine, fewer hot drinks, and less spicy food in the evening settles things; it is worth trying and watching. Try three nights without each one. That tells you which one matters for you.
Some options have been studied for menopause symptoms. Soy Isoflavones has an evidence grade of A. Its traditional tier is T0.
Black Cohosh has an evidence grade of B. Its traditional tier is T2. It is a long-used herb, and some trials back it.
Red Clover has an evidence grade of B. Its traditional tier is T2. Maca Red has an evidence grade of C and a traditional tier of T2.
If broken sleep is your worst part, look at sleep aids. Melatonin has an evidence grade of A. Its traditional tier is T0.
Magnesium has an evidence grade of A. Its traditional tier is T0. Valerian Root has an evidence grade of B and a traditional tier of T3.
Calming the stress side helps some people. Yoga has an evidence grade of A. Its traditional tier is T3.
Biofeedback has an evidence grade of A. Its traditional tier is T0. It teaches you to slow your breathing and your heart rate.
Ashwagandha has an evidence grade of A. Its traditional tier is T3. Vitamin D has an evidence grade of A and a traditional tier of T0.
Some options rest on long use, not trials. Acupuncture has a traditional tier of T3, and its evidence grade is insufficient. Flaxseed has a traditional tier of T3, and its evidence grade is also insufficient.
A Plant-Based Vegan Diet has a traditional tier of T1 and an evidence grade of insufficient. St. John's wort has a traditional tier of T2 and an evidence grade of insufficient. St. John's wort clashes with many drugs, so ask your doctor first.
A few listed options aim at other menopause symptoms, not sweats. Sea Buckthorn Seed Oil (Topical) has an evidence grade of C and a traditional tier of T3. Two probiotics are listed as well, and both have a traditional tier of T0.
Probiotics (Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri) has an evidence grade of B. Probiotics (Lactobacillus plantarum P8) has an evidence grade of C. These are used for vaginal and urinary symptoms.
Try one thing at a time. Give it a fair run before you judge it. If you add three at once, you will not know what helped.
How long it takes
Room and bedding changes can help the same night. Cutting evening alcohol often shows up within a week.
Herbs and supplements are slower. Most need four to twelve weeks before you can judge them. Keep a simple sleep note so you can see real change.
Yoga and biofeedback need practice. Most studies run them for eight to twelve weeks. Nothing here is sure to work for you.
Menopause sweats often ease over time on their own. For many people they last a few years. Some have them longer, and that is still normal.
